Ruqyah is the act of reading selected verses from the Quran over Zam Zam or normal water to ward off sorcery and magic spells. It also involves using Black Seed oil or Olive Oil to rub and massage the body, especially the head area. There are 45 verses in the Quran that have been found to work effectively against these magical spells and sorcerers.
Some of the companions of the Prophet (Allah bless him and give him peace) including Abu Qilabah wrote verses of the Quran on a clean vessel and washed them and gave the water to the ill person to drink. Also Ibn Abbas wrote two verses of the Quran for a woman suffering from hard pregnancy and washed them and then she drank them. All of this is reported in ‘Mahraas-e-Ruqyah’ by Ibn Qayyim al Jawziyyah and other reliable scholars.
Another way of writing verses and Islamic supplications on papers or any purified thing is by dipping the stamps in water containing saffron and then selling them to the people to use for recovery. However, this isn’t permissible because it violates one of the conditions of Ruqyah as Shar’eeya which is that if the person who writes and the patient both believe that it will bring recovery then they may use it.
It is also forbidden to write verses from the Quran on a dirty plate and wash it for a person to drink because this violates one of the conditions of Ruqyah. This is why it is important to make sure that the paper used is clean before reading it. dissolvable quran ruqyah paper
